Abstract
The automatic backflush filter includes one outer casing with water inlet, water outlet and blowdown outlet and one characterize valve plate shaft, which is near the water inlet inside the casing and has one backflush valve plate mounted to its upper part and one filtering valve plate mounted on its lower part. These two valve plates are semi-circular and mounted to the shaft vertically, the filtering valve plate has one L-shaped filtering board with filtering medium and filtering holes. During filtering, only the filtering valve plate is opened for water to flow through the filtering medium to the water inlet; and during backflush, only the backflush valve plate is opened for water to flow through the backflush passage and filtering medium to the filtering passage and to flush inversely out impurity in the filtering passage with the flushed impurity being drained via the blowdown outlet.
Description
Technical field
The present invention relates to a kind of hydrotreater, particularly a kind of automatic backwashing filter of removing impurity in the water by the mechanical filter principle.
Background technology
Raising along with people's quality of life; protection to natural environment has proposed new requirement; particularly to the live protection of closely bound up water resource of people; utilize particularly important again; no matter be industrial water supply; as the air-conditioning cooling circulating water system; the carwash circulating water system; boiler water system; bath system for keeping in good; the swimming pool system; and chemical industry system water such as water for pharmaceutical purposes; and well water; the filtration of river etc. all needs to carry out the filtration treatment of water; particularly current Tourism development reaches the fountain of being built that beautifies to urban environment; the boat paradise; filtration more needs to carry out in a large number the water filtration processing before sewage treatment plant and the various pump; so that water that obtains cleaning and reasonably utilization again, thereby reach protection water resource and water-saving purpose.
Because the method for traditional chemical substance filtered water seldom adopts, mostly adopt physical cleaning method filter, remove impurity in anhydrating by the mechanical filter principle, water enters the filtration water channel in the filter, by the filter medium feed system, the impurity in the filtered water road can make it carry out backwash by the water channel that changes in the filter more for a long time, remove impurity, and discharge from sewage draining exit.
As shown in Figure 1, 2, know filtration, the recoil view of backwash filter for having oneself now, this backwash filter 10 includes a shell body 11, a cartridge filter 12, a recoil valve plate 13; This shell body 11 is provided with water inlet 14, delivery port 15 and sewage draining exit 16, this cartridge filter 12 is provided with a plurality of filtering holes 121, this cartridge filter 12 is communicated with the welding of shell body 11 water inlet ends, at this recoil valve plate 13 of cartridge filter 12 installings near water inlet end, these recoil valve plate 13 central authorities are fixed on the valve shaft 17 by a steady pin 18, this valve shaft 17 passes this cartridge filter 12 rotatable being articulated on the shell body 11, this valve shaft 17 termination spiral shells knot one handles 19 are with the unlatching of controlling this recoil valve plate 13 or close; Fig. 1 is the filtration view of backwash filter 10, wherein should be the unlatching shape by recoil valve plate 13, sewage draining exit 16 is closed, when water enters cartridge filter 12 from water inlet 14, and flow to delivery port 15 after filtering by a plurality of filtering holes on the cartridge filter 12 121 and supply with water systems (shown in the direction of arrow among Fig. 1); Impurity more for a long time in cartridge filter 12, to carry out the backwash processing in order to remove impurity, at this moment, recoil valve plate 13 in the cartridge filter 12 is closed, close delivery port 15 simultaneously, open sewage draining exit 16, when the water valve plate 13 that recoiled when water inlet 14 enters stops, can only flow into cartridge filters 12 through a plurality of filtering holes 121 recoils from the space of 11 of cartridge filter 12 and shell bodies, discharge (shown in the direction of arrow Fig. 2) from sewage draining exit 16 with flushing impurity therebetween; But, in backwash process,, recoil space, valve plate 13 left side separates because being stopped by it, and can't carry out backwash to the impurity that residues in this space, and have the backwash dead angle, there is following shortcoming in this backwash filter 10:
1, when the backwash filter tube, the quality that does not thoroughly influence water is cleaned in the dead band that existence can't be cleaned in the cartridge filter;
2, can not dismantle on this cartridge filter welding shell body, can't reach thorough cleaning cartridge filter;
3, the scope of application is little, not the convenient and practical property of tool.
In view of this, for overcoming above-mentioned shortcoming, this creator is engaged in this work professional technique and practical experience for many years with it, through test and improvement repeatedly, develops the present invention finally.
Summary of the invention
The present invention will provide a kind of automatic backwashing filter, makes it reach the technical problem of removing impurity in the filter completely with solution.
It is such solving the problems of the technologies described above the technical scheme that is adopted:
A kind of automatic backwashing filter, include a shell body, which is provided with water inlet, delivery port and sewage draining exit, it is characterized in that: install a valve shaft near the water inlet end place in this shell body, this valve shaft first half is equiped with the recoil valve plate of a semicircular in shape, its Lower Half is equiped with the filtration valve plate of a semicircular in shape, this two valve plate is the cross vertical configuration mutually and is fixed on the valve shaft, this filtration valve plate right side is provided with a filter medium that is shape filter, and this shape filter is provided with a plurality of filtering holes;
This shell body is a pipe-like, and its two ends are provided with is convenient to the ring flange installing, dismantle;
This affixed one handle in valve shaft termination;
This shape filter is for detachable, and it is conical that a plurality of filtering holes on it are;
This shape filter is provided with screen pack, and its screen distance is 2.5 * 2.5mm
2
Be provided with nonwoven between this shape filter and screen pack, its aperture is 80～200 μ m.
The present invention includes a shell body, this shell body is provided with water inlet, delivery port and sewage draining exit, it is characterized in that installing a valve shaft near the water inlet end place in this shell body, this valve shaft first half is equiped with the recoil valve plate of a semicircular in shape, Lower Half is equiped with the filtration valve plate of a semicircular in shape, two valve plates are the cross vertical configuration mutually and are fixed on the valve shaft with steady pin, and this filtration valve plate right side is provided with a filter medium that is shape filter, and this shape filter is provided with a plurality of filtering holes; When automatic backwashing filter is under the filtration state, this moment, sewage draining exit was closed, this filters valve plate and opens, the recoil valve plate is closed to block first half recoil water channel path in the shell body, water can only be flowed through by water inlet, and Lower Half enters shape filter spatial filtering water channel in the shell body, flow to delivery port by the filtering holes on the shape filter and sends; And when the impurity in shape filter space more for a long time, carrying out automatic backwash handles, at this moment, then delivery port is closed, and turning handle half-twist, this recoil valve plate is opened, filter valve plate and close the inlet of shape filter, open sewage draining exit simultaneously, water can only enter shape filter spatial filtering water channel by the filtering holes on the shape filter by flow through first half recoil water channel in the shell body of water inlet, and the impurity in the shape filter space is carried out backwash, and, make it reach the technical problem of removing impurity in the filter completely thereby solved by the sewage draining exit discharge.
The present invention is simple in structure, and its advantage is as follows:
